O bed! O bed! delicious bed!
That heaven upon earth to the weary head.

In these lines Hood treats the bed as a comic-lyrical object of devotion, elevating ordinary sleep into a quasi-religious consolation: “heaven upon earth” for a mind and body worn down by labor or worry. The exclamatory repetition (“O bed! O bed!”) mimics a mock-ode, suggesting both genuine relief and playful exaggeration—typical of Hood’s blend of sentiment and wit. The couplet also reflects a nineteenth-century urban sensibility in which fatigue (physical, economic, emotional) is a defining condition, and rest becomes the most immediate, democratic luxury. The humor does not cancel the feeling; it sharpens it by making the craving for respite vivid and universal.
